Python+OpenCV: cv2.imwrite

Question

I\'m trying to detect a face and write down area with the face in a separate file. How can I do it? I think that i must use \"faces\" (you can see this var in code). But how?

Answer 1

wtluo, great ! May I propose a slight modification of your code 2. ? Here it is:

for i, detected_box in enumerate(detect_boxes):
    box = detected_box["box"]
    face_img = img[ box[1]:box[1] + box[3], box[0]:box[0] + box[2] ]
    cv2.imwrite("face-{:03d}.jpg".format(i+1), face_img)
